Question

Create a class that holds data about a job applicant. Include a name, a phone number, and four Boolean fields that represent whether the applicant is skilled in each of the following areas: word processing, spreadsheets, databases, and graphics: Include a constructor that accepts values for each of the fields. Also include a get method for each field. Create an application that instantiates several job applicant objects and pass each in turn to a Boolean method that determines whether each applicant is qualified for an interview. Then, in the main() method, display an appropriate method for each applicant. A qualified applicant has at least three of the four skills. Make sure your JobApplicant.java file runs with this file TestJobApplicants: I can not get the JobApplicant to work. Here is the program:

import java.util.Scanner;

class JobApplicant
{
private String name;
private String phone;

// boolean variables for word,spreadsheet,database and graphics skills
private boolean w;
private boolean s;
private boolean d;
private boolean g;
  
//The constructor. This needs to set all the properties of this class
public JobApplicant(String name, String phone, boolean w, boolean s, boolean d, boolean g)
{
this.name = name;
this.phone = phone;
this.w = w;
this.s = s;
this.d = d;
this.g = g;

}

public String getName()
{
return name;
}

public boolean getHasWordSkill()
{
return w;
}

//get methods
public boolean getHasSpreadsheetSkill()
{
return s;
}
public boolean getHasDatabaseSkill()
{
return d;
}
public boolean getHasGraphicsSkill()
{
return g;
}
public String getPhone()
{
return phone;
}

}

It is telling me no main methods, JavaFX Applications, applets or MIDlets found in file..HELP!!!

/*
* ------------- JobApplicant.java ----------------
* The code you have written is right but your class has no main method that's why
* you are getting that message on runtime.
* well you shouldn't write main method in the class JobApplicant because,
* in the question there is a mentioning about
* " Create an application that instantiates several job applicant objects and
* pass each in turn to a Boolean method
* that determines whether each applicant is qualified for an interview."
* and it will be tested by TestJobApplicants.java
* so i have created another java class called TestQualified.java
* where you will find a method that takes a JobApplicant object and returns
* a boolean value whether the applicant has atleast 3 skills or not.
* in TestJobApplicants.java objects for JobApplicant are created and
* also TestQualified object is also created.
* using that TestQualified object testing of each JobApplicant is done.
* you may ask that in question they said create an application that instantiates several job applicant
* but you have created them in TestJobApplicants.java, i have created them in TestJobApplicants.java
* because the code of the TestJobApplicants is not given and there is a confusing.
*
* so you save three files JobApplicant.java and TestQualified.java and TestJobApplicants.java
* if you want any modifiications please comment and if the code is reached your expectation
* please like the answer.
